Just a few years ago, insiders and experts wrote us off and assured the world Keystone XL would be built by the end of 2011. Together, ranchers, tribal nations and everyday people beat this project back, reminding the world that Big Oil isn’t invincible—and that organized people can win over organized money.

UPDATED: After seven years of deliberation, the Obama administration rejected the Keystone XL pipeline on Friday. The proposed 1,179-mile pipeline would have carried 800,000 barrels a day of carbon-heavy petroleum from the Canadian oil sands to the Gulf Coast.

Inspired by journalist Naomi Klein’s best-selling book, “This Changes Everything,” a new documentary of the same name re-imagines the vast challenge of climate change. The film, which opens Friday, profiles communities on the front lines of the climate justice movement—from Montana’s Powder River Basin to the Alberta tar sands, from the coast of South India to Beijing and beyond.
